First of all, a big thank you to Ty for meeting up with me on Sunday night to plug the laptop into my bug in the freezing cold. No fault codes at all, so it looks like the problem isn't a misfire after all

Big problem seems to be the air/fuel ratio, which is very high. Car seems to be overfuelling and running very rich (which i assume accounts for the high emissions) The previous owner fitted a powertec induction kit, but there is no cold air feed to the cone. Planning on fitting a cold air feed from the fog cover this week, how much of a difference will this make? Also, the exhaust is blowing somewhere forward of the centre section, which also needs to be sorted. Will these two fixes alone solve the overfuelling problem and is there anything else i need to be looking at? Cheers guys.

No problem Phil, glad to be of help.

What was 'interesting' was the the ignition advance/retard was all over the shop plus lambda readings were high as well.

Anyway good luck in sorting it out.

Was it pinking its ***** off. Check knock sensor and how many lambda sensors has it got.

hi

when my bug went for mot i had the same sort of filter as you do and the emmissions was through the roof after taking the filter off fitting a standard airbox back to the car the car flew the test i would take the filter off and use oem with a decent pannel filter ie cotton green or cosworth even after mapping with the standard air box my car still made better bhp/llbs with the oem air box than the cone

hope this helps a bit

I don't think it was pinking, there were no recorded faults but the readings were high.

There was a quite bad exhaust blow so I wonder if the lambda readings were forcing the ignition and fuelling, but I think the exhaust blow needs sorting before anything else.

when you plugged the laptop in was the 02 sensor`s cycling ? or the reading slow to alter?
again what was the maff doing voltage wise ?

The o2 sensor was up and down altering all the time, the car has no MAF sensor well not in the usual location if it is there - the induction kit feeds directly into the intake housing at the back end of the engine.

I checked earlier and I forgot to save the datalog.

no

thought op car was a wrx
